ISS012-S-001 (September 2005) --- The Expedition 12 patch represents both mankind's permanent presence in space and future dreams of exploration. The International Space Station (ISS), featured prominently in the center, will continue to grow in its capability as a world-class laboratory and test bed for exploration. The vision of exploration is depicted by the moon and Mars. The star symbolizes mankind's destiny in space and is a tribute to the space explorers who have been lost in its pursuit. The Roman numeral XII in the background signifies the 12th expeditionary mission to the ISS. The NASA insignia design for Shuttle flights and Space Station increments is reserved for use by the astronauts and cosmonauts and for other official use as the NASA Administrator may authorize. Public availability has been approved only in the form of illustrations by the various news media. When and if there is any change in this policy, which is not anticipated, it will be publicly announced.
